Key Ingredients
A 44-amino acid synthetic GHRH analogue with enhanced stability. Research documents pituitary somatotroph activation and growth hormone release through the GHRH receptor pathway.
Tesamorelin is a synthetic analog of growth hormone-releasing hormone (GHRH). It consists of the 44-amino-acid sequence of human GHRH with an additional trans-3-hexenoic acid modification at the N-terminus, which enhances its stability and bioactivity.
Research Background
Tesamorelin stimulates growth hormone release from the anterior pituitary via the GHRH receptor. Clinical research has studied its effects on visceral adipose tissue reduction and the GH/IGF-1 axis. The nasal spray format enables research into intranasal delivery of large peptide analogs. For research purposes only.

GHRH Analogue
Synthetic GHRH analogue for growth hormone axis research
Tesamorelin is a synthetic analogue of growth hormone-releasing hormone (GHRH) with a trans-3-hexenoic acid modification. It stimulates pituitary somatotroph cells to produce and release growth hormone through the GHRH receptor.
